The Science of Public Speaking

Some good info:

How to Speak

Every January, during MIT’s Independent Activities Period, Computer Science Professor Patrick Henry Winston gives a famed lecture titled: How to Speak. During this perennially popular event, Professor Winston walks his audience through a series of tips and strategies, developed and honed over decades, for mastering the art of speaking. I attended his lecture for the first time this year, and was not disappointed.

The crowd was literally at capacity. Every seat filled. Every step filled. The ground surrounding the podium filled. And a crowd spilling out into the hallway straining to hear. Having arrived early, I was able to snag a desk an thus take copious notes. In this post, I draw from these notes to present to you, in detail, the secrets behind the Patrick Winston Method.

The Formula

I = f(K,P,T)

Your Impact is a function of your Knowledge about speaking, Practice, and Talent �?? in decreasing order of importance. Winston’s advice focuses on your knowledge about speaking. This is the easiest way to gain the biggest increases in your impact.

How to Start

Some advice for starting your talk.

  1. Don’t start with a joke. The audience is not accustomed to you or your speaking style yet. Humor will be difficult at this point.

  2. Do start with a menu. Tell them exactly what you’ll be speaking about and in what order.

  3. Do provide an empowerment promise. Explain why your audience will come away from the talk better than when they entered.

The Big Four

A collection of four heuristics that make a talk work.

  1. Cycling. Deliver ideas first in brief, then in detail, then in summary. To use the lingo of artificial intelligence: let your audience load the schema, then fill in the details, then let them know what’s worth indexing for future reference.

  2. Verbal Punctuation. Provide a mechanism to help people who “fogged out” to easily rejoin the talk. For example: “We have just finished talking about the first heuristic, cycling, I am now going to talk about the second heuristic for helping to make your talks more interesting�?�”

  3. Near Miss. When explaining an idea, also describe other ideas that are close but not quite the same. This will help people understand what the important points are that define your idea.

  4. Ask Rhetorical Questions. Don’t make them too easy. Don’t make them too hard. Wait 6 seconds for an answer.

The Tools

Four tools that can make or break your presentation.

  1. Time and Place. If it’s in your control: mid-morning is the best time. Choose a location that will look full with your expected audience size. Make sure it is well-lit. Don’t let them turn down the lights. (“It’s easier to see slides in a light room then to seem them through closed eyelids.”)

  2. The Board. A blackboard lets you draw natural graphics that highlight your points. It also paces you. The speed of writing matches the speed with which people process information. Use a logo that captures the main point and that you can return to. (“I once saw a Sloan professor lecture for a whole hour about a triangle; it was amazing!”) It also provides a target. The best thing to do with your hands? Point at things on the board.

  3. Slides. Don’t use anything less than 24-point type. If you can’t fit the information at this font size then you have too much. Follow these four rules:

    A. Don’t read the slides! “A special circle in hell for those who�?�”

    B. Don’t stand far away from the screen. This requires divided attention from your audience.

    C. Have one meaningful picture per slide. If it’s found in Microsoft’s clip art gallery, it’s not meaningful.

    D. No pointers. Laser or otherwise. These are distractions. You’ll play with them. They’re annoying. Stand by the screen and point with your hand or refer to visual anchors on the slide.

  4. Props. When possible, use a prop to illustrate an idea.

Special Cases

Three specific types of talks. (Notice, the first two are specific to academia, but the advice is none-the-less generalizable to other arenas).

  1. Oral Exams. Some strategies:

    A. Show your hand early on. Within five minutes have explained what you did and why it’s important.

    B. Situate your results in time, space, and field. That is, explain the trajectory over time of your area of concentration, where else people are working on the same problem, and the consequence of your result for the field.

    C. Practice. Ask your friends to listen to your talk. Tell them to try to make you cry.

  2. Job Talk. Here is what they want to see in a candidate:

    A. Has a vision.

    B. Has done something about that vision.

    C. Don’t finish with a conclusion slide. Instead have a contributions slides. Something that spells out clearly what you did.

  3. Getting Famous. If you want to become a world class speaker, try to deploy Winston’s Star. A five-point checklist of things to make your talk extra memorable:

    A. Symbol. Some icon that makes your ideas easy to hold on to.

    B. Slogan. A simple linguistic handle for your ideas.

    C. Surprise. Make people say: “did you see that talk�?�”

    D. Salient. Have an idea that really sticks out.

    E. Story. Tell stories that engage the audience.

How to Stop

Some things to keep in mind about concluding a talk:

  1. Deliver on your promise made at the beginning. Remind them what it was and summarize how you satisfied it.

  2. Tell a joke. They know you now. And if they leave happy they will assume the entire talk made them happy.

  3. Call for questions.

  4. Don’t thank the audience. It makes it seem like they did you a favor by listening to your boring babble.

  5. End with a salute. Compliment without thanking. (i.e., “You’ve been a great audience, I hope you learned a lot about how to give a great talk.”)

Really good stuff in there. Heuristics is a lost art form.

Thanks for that. Saved for future reference.

Really good post. I’ve also been told regarding Powerpoints that you should have no more than 1 for every 2-3 minutes of the talk.

Thats a good article…since public speaking puts the fear of god in people. For me, its hard to contain the anxiety…the adrenaline that comes. Once I’ve slightly harnessed that energy, then I have the problem to deal with that I somehow separate from myself as I’m speaking, so I’m saying the right words…but feel like I’m a bystander of myself. So the emotion or impact of what I’m saying seems sort of…flat. Does that happen to anybody else? It’s like another part of me is judging me and having inner dialog at the same time. I can’t seem to invest in the material, even when the material involves things I’m passionate about. Meh, I got good grades in public speaking regardless, but it would be a challenge to do it on a constant basis.

I don’t have that problem when I sing on stage…of course the adrenaline and such, but that seems to help with the emotion overall, and I can connect to the music and disappear, from my inhibitions. Time stops and the world stops…if self were to knock I’d say, not now chief I’m in the fucking zone. ;o)

/me time over.

I don’t mean to stray too far off topic, but I’ve been researching the use of beta-blockers for public speaking. I mean everyone is a little nervous or has a small fear of speaking in front of large crowds, but for others (me) it has a huge impact on furthering my goals. I get to the point where I almost black out and get scared that I am gong to faint.

It is not that I am a “shy” person. I am very friendly and feel very comfortable talking to strangers, but when put in front of a crowd I freak out. It has become a serious issue for me.

Has anyone else had any experience using prescription meds for speech anxiety? I have also gone so far as to consider hypnosis as a possible solution.
